What is the name of the type of cell division that occurs in the prokaryotic cell cycle

What is the significance of the protein-lined pits? a. protein attracts other proteins needed for atp synthesis within the cell. b. protein-lined pits are able to transport one molecule at a time down the concentration gradient within the cell. c. the polarity of proteins allows other polar molecules to attach and be transported in the cell by transport channels. d. receptors within the pits allow ligands to fuse and be transported into the cell by endocytosis.

This is a scaffolding of protein fibers that us sell keep it shape in a cell division and cell movement
